PENNSYLVANIA, A CORPORATION OF CAR ROOF.

Application flled November 3, 1926. Serial No. 145,963.

This invention relates to car roofs and has for its principal object to provide a simple and efficient roof that will readily adapt it self to the distortions of the car body incident to service conditions. Other objects are cheapness of construction, compactness of design, fewness of parts, and ease of as sembly. I

The invention consists principally in an eaves clip adapted to hold the sheets down on the car at the eaves, said clips being pro vided with an abutment surface which limits outward sliding movement of the sheets and is shaped to permit the eaves ends of the sheets to rock thereon. The invention also consists in the construction and arrangement of parts hereinafter described and claimed. I I

In the accompanying drawings, which form part of this specification and wherein like symbols refer to like parts'wherever they occur.

Fig. 1 is a plan View of a portion of a car roof embodying my invention, .parts being.

Fig. 6 is a perspective View of one of the eaves clips.

Referring to the accompanying drawings, my invention is shown in connection with a common type of roof frame or substructure comprising side plates 7, carlines 8, side sheathing 9 and. fascia-boards 10. A ridge pole 11 and purlines 12 rest on and are rigidly secured to the carlines; and a series of spaced parallel wooden battens or 'mullions 18 extend transversely of the car from eaves to eaves thereof across the tops of the side plates, purlines and ridge pole and are rigidly secured thereto. The upper corner of each side plate 7 is rabbeted or offset to a taken through me 5-5 in Fig.

on the line 3+3 in 5 is a vertical section through the lower level than the main surface thereof; and the upper edges of the side sheathing 9 and fascia 1O terminate flush with the surface of said rabbet to form outward extensions thereof. A metal eaves flashing strip 1 1 has a body portion which rests flatwise in said rabbet and has its inner marginal portion 15 rebent or doubled-back over said body portion but spaced slightly therefrom; and the outer margin of said flashing strip is bent down over the fascia and nailedor otherwise rigidly secured thereto.

Supported on the side plates, ridge pole and purlines between adjacent battens are metal roof sheets 16, which extend from eaves to ridge of the car. Said roof 15 of the eaves flashing strips 14:. The ridge margins ofthe sheets are provided with upstanding seam flanges 18; and the side margins of said sheets are flanged upwardly and are thence bent inwardly over the bodies of thesheets to form side seam flanges 19 of substantially inverted L-shaped section. The side seam flanges 19 of the sheets on opposite sides of the battens are loosely connected to each other by inverted channelshaped transverse seam covers 20 that straddle said flanges and said battens and have outstanding base flanges 21 that rest on the body portions of said sheets. The transverse seam covers have downwardly curved eaves'end portions that merge into the plane of the base flanges of said seam covers at the ends thereof where they are rebent on provided with downwardly opening cross grooves or channels that straddle said ends oi said seam covers. The corner caps are secured to the ridge pole by vertical on said convex abutment surface.

bolts 26, which also secure the running board saddles 27 in position. Running boards 28 rest on said saddles and are secured thereto in any suitable manner.

Located at the eaves of the car, midway between adjacent root battens or mullions, are eaves clips 29. Each of said eaves clips comprises a body portion which rests flatwise on the body portion of the eaves flashing strips 14- and a depending outer end portion or flange 30, which overl'iangs the die pending flange of said eaves flashing and is rigidly secured to the car preferably by means of horizontal bolts 31. The body portion of said eaves clip extends inwardly beneath the doubled-under eaves flange 17 of the root sheet beyond the free edge thereof and has its inner marginal portion rebent or doubled-back to torm a flange 32 which extends between said doubled-under flange o'f said root sheet and the doubledback flange 15 of the eaves flashing 14. The doubled-back flange portion 32 ot the eaves clip terminates in a depending abutment flange 33 having an outstanding lip 34 at its lower edge. As shown in the "drawing, the free marginal portion of the doubledunder eaves flange 17 of each sheet is oflset upwardly beneath the doubled-back flange portion 32 of the eaves Clip to form an upstanding shoulder 35 adapted to abut against depending abutment flange 33 of said eaves clip and thereby limit the outward sliding movement of the sheet. As shown in the drawing, the depending abutment flange 33 of the clip is bowed or curved from end to end of said flange, the direction of curvature being such that said abutment flange presents a convex surface to the shouldered portion 35 formed by the upwardly offset free marginal portion of the doubled-under eaves flange 17 of the sheet.

By the arrangement described, each roof sheet has pivotal tangential contact midway of its eaves ends with the convex abutment surface of an eaves clip, and is thus adapted to accommodate itself automatically to the distortions of the car frame by a rocking or sluing movement of its eaves end portion The eaves clips also cooperate with the eaves flashings in holding the sheets down on the car at the caves; and they also serve to limit sliding or bodily movement crosswise of the car and maintain suflicient clearance or play at the ridge and eaves ends of the sheets to permit the roof sheets to slue on said clips without damage to the sheets, seam covers,

. or eaves flashings.

The invention is applicable to roots having various forms of flexible ridge and side seam constructions and substructures; therefore, I do not wish to be limited to the precise construction shown and described.

lVhat I claim is: l

1. A flexible car roof comprising root sheets whose eaves end portions are rebent, and means cooperating with the rebent eaves end portions of said sheets for securing a sluing movement of said sheets about points located at their eaves ends.

2. A flexible car roof comprising root sheets whose eaves end portions are rebent and formed with shoulders, and a member secured to the car at the eaves and cooperating with the rebent and shouldered eaves end portions of said sheets for holding said sheets down on the car at the eaves and for limiting bodily movement thereof transversely of the car.

3. A flexible car roof comprising root sheets whose eaves end portions are rebent and movably interlocked with rebent flashing strips, and means cooperating with said flashing strips for holding said strips down on the car and with the rebent eaves end portions of said sheets for securing a pivotal movement of said sheets about points located at their eaves ends.
